DIP-Switch Descriptions

• S1: Set the control signals

- S1.1: Set the DPRSLPVR signal

- S1.2: Set the DPRSTP# signal

Jumper Descriptions

• J16: If installed, the +5V rail supplies the +3.3V rail

to the auxiliary circuit on the board. DO NOT APPLY

+3.3V TO TP37/TP30 WHILE J16 IS

INSTALLED! IT’LL SHORT THE +5V AND THE

+3.3V POWER SUPPLIES. When measuring board

efficiency, uninstall J16 and apply +3.3V to

TP37/TP30.
